276 NATURAL HISTORY OF PLANTS. 



Petals oblong-lanceolate, twisted at base, long-unguiculate. Stamens 

 free. Siliqua elliptical or lanceolate compressed ; style very short ; 

 apex stigmatose, globose or subcorneal ; valves flat reticulate ; septum 

 membranous or spongy {Machcerophorm*). Seeds cc, 2-seriate im- 

 marginate ; embryo sometimes coloured ; cotyledons incumbent. — 

 Underslirubs, branching leafy hoary tomentose ; leaves entire or 

 pinnatifid ; flowers- racemose ebracteate terminal {Chili, Pei'if). 



121. Ammosperma Hook, f. 4 — Sepals erect; lateral more or less 

 saccate at base. Petals obovate, long-unguiculate. Stamens 6, 

 4-dynamous ; filaments free toothless. Siliqua very shortly stipitate, 

 narrowly linear elongated compressed ; style short ; apex stigmatose 

 capitellate subtruncate ; valves flat minutely torulose, sometimes 

 depressed at middle ; septum hyaline. Seeds ex, minute, 2-seriate 

 oblong-compressed ; embryo rather fleshy (coloured) ; cotyledons 

 incumbent. — A much branched hoary pubescent herb; branches 

 terete leafy ; leaves pinnatifid ; flowers 5 in terminal racemes, re- 

 motely alternate; pedicles slender, ebracteate {Tunis 6 ). 



122. Leptaleum DC. 7 — Sepals linear erect, subequal at base. 

 Petals linear-angustate. Stamens 6 ; longer connate in pairs. Siliqua 

 linear sessile, weakly dehiscent or indehiscent ; style short conoidal ; 

 lobes 2, stigmatose connate ; valves rather flat coriaceous, 1 -ribbed, 

 net-veined ; septum complete excavated subfungous. Seeds cc, 

 close, 2-seriate small, broadly oblong obtuse, echinulate outside. — A 

 small annual much branching herb ; branches thin ; leaves linear or 

 filiform, entire or multifid ; flowers 3 axillary, or in short subspicate 

 few-flowered racemes {The Easf). 



c. SfccovinE-E. — Cotyledons usually conduplicate.
